I thought that was the thread, but I guess I could have forgotten to copy the right thread. Until yesterday, that thread only went to 5/8 and my 5/21 post was minutes after I read the original post. I did a quick look and couldn't find the post. I'll try again in a bit. I thought there were more posts in that thread. Maybe TL cleaned up that thread?
Anyway, I didn't recognize the poster, but she said that she was on Android and deleted wall posts (a normal activity for her). She said then 2 of her neighbors were blocked from posting if they went to her wall from theirs, but could if they went from their neighbor list.
I also saw a post a day or two before where and Android player said that neighbors said they were blocked but he/she didn't block them.
